1 Claim. (Cl. 304-) This invention relates to scaifold supportingstructure. While the invention might have many applications, itparticularly is designed and illustrated as a support for holdingtimbers forming a scaffold, which scaffold supports operators forworking on or erecting walls of a building, and is a division of ourcopending application, Serial No. 745,280, filed May 1, 1947.

It is an object of this invention to provide a scaffold supportcomprising an elongated member or bar adapted to extend in horizontalposition, the same having at one end means constructed and comprising aground-engaging support, said support preferably sloping toward saidwall.

It is a further object of the invention to provide a scaffold supportcomprising a horizontally extending timher-supporting member, means atone end of said member such as an angle bar or T-shaped bar adapted toextend into a wall between the bricks or other members thereof, saidmember having connected adjacent its other end a vertically extendingmember adapted to be held in different positions in a supporting membercomprising upwardly converging bars which preferably slope toward saidWall and are separated quite a distance at their lower ends in adirection substantially parallel to said wall.

These and other objects and advantages of the invention will be fullyset forth in the following description made in connection with theaccompanying drawings in which like reference characters refer tosimilar parts throughout the several views and in which:

Fig. 1 is a view in side elevation of a scaffold support embodying thepresent invention, certain parts being shown in vertical section, saidview also showing a portion of a wall and a portion of a scaffold invertical section;

Fig. 2 is a top plan view of the device shown in Fig. 1;

Fig. 3 is a horizontal section taken substantially on line 3-3 of Fig.l, as indicated by the arrows;

Fig. 4 is a horizontal section taken substantially on line 44 of Fig. l,as indicated by the arrows; and

Fig. 5 is a partial view in perspective showing one end of the devicedisposed in a wall.

Referring to the drawings, a scaifold support is shown comprising anelongated member adapted to be disposed in horizontal position. Whilemember 20 might take various forms, in the embodiment of the inventionillustrated, it is shown as a T-bar having its flange extendinghorizontally and its central web extending vertically downward. Member20 has secured to one end thereof a member 21. While member 21 could bevariously formed, it is illustrated as a T-bar having the top of itsflange resting on top of the flange of member 20 and having its centralweb extending vertically. Member 21 is thus in inverted positionrelative to member 20. Member 21 is constructed and arranged to beconveniently disposed in a wall 22 of a building. The vertical web 21athereof can conveniently be disposed between the ends of a pair ofbricks 22a forming said wall and the side portions of the flange 21b canconveniently be disposed between the adjacent side of verticallyadjacent 2,731,393 Patented Jan. 17, 1956 bricks. This is clearly shownin Fig. 5. The end of member 20 can abut the outer surface of wall 22,as shown in Fig. l. A vertically extending member 24 is provided andwhile this might take various forms, in the embodiment of the inventionit is shown as a cylindrical member and specifically as a pipe. A clip25 shown as formed of a pair of flat steel plates are secured to pipe 24in any suitable manner, as by welding. Clip 25 has spaced sides 25bprojecting at one side of pipe 24 and these are disposed at either sideof the web 20a of member 20 and secured thereto in any suitable manner,as by the rivet 26. Member 24 has a slot in its upper end receivingflange 20a. Member 24 is disposed in and slidable in another cylindricalmember 27. Member 27 has formed in its top a plurality of verticallyextending slots 27a open at their upper ends. Member 24 is provided witha series of vertically spaced holes 24a. A pin 28 is adapted to bedisposed in any one of the holes 24a and to be received in a pair ofoppositely disposed slots 27a. Slots 27a are circumferentially spacedand four of these are shown degrees apart. A ground-engaging support 30is provided and while this might be variously formed, in the embodimentof the invention illustrated it comprises upwardly converging members orbars 30w having their upper ends engaging the sides of member 27. A yoke31 which is illustrated as formed from a rod has its ends extendingacross one side of members 30a respectively and secured thereto in anysuitable manner, as by Welding. While members 30a might be variouslyformed, they are illustrated as angle bars. Yoke 31 is bent inwardly atits central portion so as to engage member 27 and is connected to member27 in any suitable manner, as by welding. Member 27 is thus firmly andrigidly secured to the upper end of the support 30. Support 30 alsocomprises a plurality of bracing members 3012 shown as rods extendinghorizontally between and engaging the sides of bars 30a to which theyare connected in any suitable manner as by welding. A chain 32 isconnected to one end of pin 28 and is connected at its other end to oneof the bars 30a.

In operation when wall 22 is to be built, the bar 20 can be disposed asshown with member 21 disposed in the wall, and the other end of bar 20will be supported, as shown in Fig. l, by member 24 and support 30.There will be two or more of the devices and boards or joistlike timbers34 can be laid on top of members 20 and extend between the same. A veryconvenient scaffold is formed by members 34 and the operators can standon this scaffold and continue to build wall 22 upwardly. When the wallis up to a sufficient height, member 21 can be withdrawn from betweenthe bricks 22a and the space occupied by said member can be filled withmortar or cement. Member 24 can be raised in position and the scaffoldcan be again positioned at a higher level. It will be noted that support39 slopes upwardly and toward wall 22. The scaffold can be easily andquickly folded into compact shape when not in use so that it can beeasily and conveniently stored or transported. In fact, member 29 canswing about pivot 26 so as to come into substantially parallel relationwith member 24.

It will, of course, be understood that various changes may be made inthe form, details, arrangement and proportions of the parts, withoutdeparting from the scope of applicants invention, which generallystated, consists in a device capable of carrying out the objects aboveset forth, in the parts and combinations of parts disclosed and definedin the appended claim.

What we claim is:

In a scaffold supporting structure, an. elongated horizontal timbersupporting member having a free end portion adapted to be disposed in awall, a vertical post-like member horizontally pivoted to the other endportion of said horizontal member for upward and downward pivotalswinging movements or" the free end of the horizontal member generallyparallel thereto, the horizontal member being otherwise free andunsupported, a tubular guide member in which said post-like member isaxially slidaoly mounted, means for locking the post-like member invarious different adjusted positions in the tubular member, an inclinedsupport comprising a pair of ground-engaging legs rigidly anchored tothe tubular member at their upper ends and diverging downwardly withrespect to one another and the tubular member and post-like member, saidlegs supporting the tubular guide member and postlike member with thelower end of the latter spaced above the ground, the said pair of legsdiverging downwardly References Cited in the file of this patent UNITEDSTATES PATENTS 898,368 Humphries Sept. 8, 1908 1,175,522 Horn Mar. 14,1916 1,611,376 Reiman Dec. 21, 1926 1,853,566 Lingo Apr. 12, 1932
